While selecting a test to use in his private practice, Kent discovered that a particular test was not very consistent or stable over time. In other words, a test-taker's score varied each time he or she took it. Kent can most likely infer that:

a. the test is biased

b. the test has a poor evidence of validity

c. the test makers did not use an appropriate norming sample

d. Correct the test has poor evidence of reliability
